METALLIC-LEAF-APPLYING ATTACHMENT r03 PRI TING rREssEs.

Application filed. May 3,1924. Serial No. 710,714.

To all whom it may concern:

Be it known that; I, JAMES O. OooN, a citizen of the United States ofAmerica, residing at Brooklyn, in the county of Kings and State of NewYork, have invented certain new and useful Improvements inMetallic-Leaf-Applying Attachments for Printing Presses, of which thefollowing is a specification.

This invention relates to the art of apply ing gold, silver, or aluminumleaf, or the like, to a paper or other surface. While many specialmachines have been devised for this purpose, such machines are expensiveand are usually adapted for no other purpose. For purposes ofillustration, I have selected a press in which both the platen and bedoscillate, but it'will be obvious that my invention is equallyapplicable to other types of presses, such as those in which only theplaten oscillates.

One object of my invention is to devise an attachment for ordinary smallprinting presses which will apply the leaf. automatically to a sheet ofpaper or the like during the running of the press in the same manner aswhen run for printing. My attachment may be manufactured as a separatearticle of manufacture, easily placed on the press and removed when ajob is finished.

A further object of the invention is to improve metallic leaf applyingmachines by rendering them more completely automatic in character, sothat fancy labels and the like may be leaf printed (or embossed) withgreat rapidity. Other objects of my invention will appear as thedescription proceeds.

Referring to the drawings in which what I now consider the preferredform of my invention is shown Fig. 1 is a side elevation of a standardjob printing press with my attachment mounted thereon.

Fig. 2 is an-enlarged detail of the pawl and ratchet feeding mechanismfor the strips.

Fig. 3 is a cross section of the throwout cam for stopping the feed.

Fig. 4 is a top view of my attachment showing the guide rollers and feedrollers.

Fig. 5. is a detail of the throwout lever mechanism.

Fig. 6 is a cross section of the pawl and ratchet feed mechanism shownin Fig. 7.

Fig. 7 is a diagrammatic View showing a modified form of the throwoutcam.

Fig. 8 is a sectional View of the burners at the back of the matrix.

The standard parts of a small printing press will at once he recognizedin Fig. 1. The fixed frame is shown at 1 on which is pivoted the usualplaten 2. The large flywheel pulley 3 is j'ou'rnaled on shaft 4 and maybe driven from a motor 5' by a belt 6. Pinion 7 on said shaft 4' drivesgear 8 on which is pivoted at 9 a crank 10, which oscillates the bed 11of the press. Said crank is connected, however, to the oscillatingmember 12 pivoted on the bed, which usually serves to ink the type, butfrom which the inking rollers have been removed. Platen 2 is connectedto member 12 by link 13 to give the former an oscillatory movement. Theusual throwout lever is shown at 14. The bed plate is adapted to holdthe usual type.

matrix 15. All of the above described parts are well known in the art ofpresses.

To convert the press into a leaf applying or stamping machine, I replacethe usual inking pad on top of the bed by special mechanism 16comprising a plurality of rollers 17and 18 journaled 1n, parallel sidebars The upper rollers 17 receive the white or plain paper on which thelettering is stamped while the lower rollers 18 receive the gold orother leaf paper 41. Each strip is fed from a roll 40, 41 pivoted on thebase of the bed. One of the upper rollers 17 is shown as mounted onpivoted bracket 20, which may be adjusted to bring the knife in theproper relationship to the lettering. Automatic feeding of each strip ofpaper is provided by means of the feed rollers 21 and 22 which grip therespective strips between the surfaces thereof and the smaller rollers17" and 18.

Preferably I provide an independent intermittent feed for. each feedroller. On the shaft 23 of roller 22 is secured ratchet wheel 24, whileloosely mounted on said shaft is a second ratchet wheel 25' to the faceof which. is secured gear 26. Meshing with said gear is a pinion 27 onthe shaft 28 of upper feed roll 21. Both pawls 29 and 30 for the tworatchets 24 and 25 are pivoted on" an arm 31 loosely journaled on shaft28 and oscillated by link 82 from member l2" see Fig. 1), so both pawlsare oscillated together. A cam agamst turning.

I may also provide a knife mechanism to sever the printed strip intogiven lengths. As shown, this mechanism comprises a knife pivoted at 46and linked at its outer end to a link 47. Said link in turn is pivotedat its other end to the lever 48 and intermediate its ends to a secondlever 50. Both of said levers are pivoted to an extension 51 on theframe, thereby forming a parallel linkage. Lever has pivoted to itsouter end a rod 52 which is clamped in a bracket 53 pivoted to member 12at 54. By this means it will be seen the knife is given a cutting strokefor every oscillation of the member 12. The length of each strip severedis controlled by varying the rate of feed.

The used gold-leaf paper may, if desired, be rerolled as by providing aroller 55 at the back of the machine (Fig. 4), which may be turned fromthe shaft 23 as by pulley 56, belt 57 and pulley 58 on the shaft 59 ofthe roller 55. I If desired also, the printed paper may be rerolledinstead of cutting the same into strips or labels. If this is desired,the same or a similar roller 55 may be employed for this purpose.

Preferably I provide means for quickly stopping the feed and thusinterrupting the printing operation without stopping the entire machine.For this purpose I make use of the regular throwout handle 14 of thepress as shown in Fig. 5, which shows a view looking in the reversedirection from Fig. 1. The handle 14 is connected through linkls 58, 59,and 60 and lever 61 to an arm 62 on a cam member 63, which is mounted onthe hub 80 of disc 68, said disc in turn being mounted on shaft 23. Saidmember 63 is provided on the face thereof with cam surfaces or lugs 64which take in apertures 65 in an adjacent member 66 on a shaft 23.

When member 63 is rotated with respect to member 66, the lugs 64 ride upon the edges of the apertures 65 and push the member 63 to the right inFig. 3. This forces cam 67 to the right, said cam being'the back of disc'68 which supports member 63. raises the rod 70 (Fig. 2 and 3) which inturn lifts the lever 71, having a cross bar 81 attached thereto, therebyraising both pawls clear of the ratchet teeth so that the feed isstopped. Member 63 is normally pressed to the left by means ofspringpressed plungers 7 2 and 73.

This

ily be seen when the cam is turned clockwise in Fig. 7 that the lever 71will be raised to lift the pawls as in the other form of the invention.

From the foregoing. the operation of my invention will be readilyunderstood. The movements of the press proper are exactly the same aswhen used as a printing press. Twosheets of paper are, according to myinvention, fed across the face of the type, one being the paper or otherarticle to be stamped with the gold leaf, and the other the gold leafpaper. As the two strips are fed across the face of the type, the bed ofthe press and the platen are brought together in the usual manner andthe gold transferred to the paper where the type is pressed against theback of the gold paper. Both strips are fed together automatically bythe mechanism described, the feed of each being varied at will by meansof the adjustable cams 34 and 35. The printed strip may be severed aftereach print by means of the knife 45 as described while the wholeprinting operation can be instantly arrested by throwing the handle 14thereby stopping the feed.

In accordance with the provisions of the patent statutes, I have hereindescribed the principle of operation of my invention, together with theapparatus, which I now consider to represent the best embodimentthereof, but I desire to have it understood that the apparatus shown isonly illustrative and that the invention can be carried out by othermeans. Also, while it is designed to use the various features andelements in the combination and rlations described, some of these may bealtered and others omitted without interfering with the more generalresults outlined, and the invention extends to such use.
